Circulating angiogenic cell response to sprint interval and continuous exercise.

Introduction: Although commonly understood as immune cells, certain T lymphocyte and monocyte subsets have angiogenic potential, contributing to blood vessel growth and repair. These cells are highly exercise responsive and may contribute to the cardiovascular benefits seen with exercise.

Purpose: To compare the effects of a single bout of continuous (CONTEX) and sprint interval exercise (SPRINT) on circulating angiogenic cells (CAC) in healthy recreationally active adults.

Keto-adaptation enhances exercise performance and body composition responses to training in endurance athletes.

Background: Low-carbohydrate diets have recently grown in popularity among endurance athletes, yet little is known about the long-term (>4wk) performance implications of consuming a low-carbohydrate high fat ketogenic diet (LCKD) in well-trained athletes.

Methods: Twenty male endurance-trained athletes (age 33±11y, body mass 80±11kg; BMI 24.7±3.
